Abstract

SOFCRoll is a self-supporting, double spiral design combining the advantages of the planar system, thick film manufacturing techniques and robustness of the tubular design. SOFCRoll cells are produced entirely by tape casting and co-sintering, with a volume of less than 2.5cm3 and a large active surface area that exceeding 20cm2. We are currently investigating the incorporation of the A-site deficient, nickel doped perovskite La0.43Ca0.37Ni0.06Ti0.94O3-γ into the SOFCRoll. In the SOFCRoll with La0.43Ca0.37Ni0.06Ti0.94O3-γ - Zr0.92Y0.08O2-γ fuel electrode, the Zr0.92Y0.08O2-γ electrolyte and (La0.8Sr0.2)0.95MnO3 - Zr0.92Y0.08O2-γ oxygen electrode, the electrochemical poling at 2.3V for a few minutes triggered exsolution of nickel nanoparticles and increased the power density. This paper will present the complete methodology behind SOFCRoll manufacture and ceramic processing, with the results of microstructure analysis, shrinking of individual components and recent performance tests.
